STABLE12-rx-protect-queue-during-debug-20040601

FIXES 4811

"in rx_packet.c:rxi_ReceiveDebugPacket() the rx_idleServerQueue is
scanned without taking a lock first.

The queue_Remove macro zeroes the ->next field (luckily), but this can
lead to a crash when Murphy strikes and the entry gets removed during
the scan: queue_Scan will dereference 0x0 -> next.
"

(cherry picked from commit 8d442bea4f760366b0c2bb2053e0ebf6ffa3d5c6)
